The availability of combination antiretroviral therapy has changed the lives of millions of people living with HIV (PLWH), for whom a once fatal infection can now be a manageable chronic disease. Yet only 30 percent of PLWH in the United States are virally suppressed, and significant gaps in access to care persist. While programs to boost linkage to and retention in HIV care are critical to improving the health of PLWH, efforts to evaluate these programs are surprisingly scarce. Using cutting-edge implementation science, this book tackles the issue of how to better link and retain PLWH in ongoing primary medical care. A multipart case study examines successful strategies and provides detailed profiles of the organizations involved and their processes for reaching, linking, and retaining PLWH. Barriers to and facilitators of implementation are explored qualitatively, network analysis is used to assess changes in interagency collaboration among organizations serving PLWH, and evidence-based recommendations are offered for improving linkage to HIV care in the US.

The Workshop on Self-sustaining Systems (S3) is a forum for the discussion of topics relating to computer systems and languages that are able to bootstrap, implement, modify, and maintain themselves. One property of these systems is that their implementation is based onsmall but powerfulabstractions;examples include (amongst others) Squeak/Smalltalk, COLA, Klein/Self, PyPy/Python, Rubinius/Ruby, andLisp.Suchsystemsaretheenginesoftheirownreplacement, giving researchers and developers great power to experiment with, and explore future directions from within, their own small language kernels. S3 took place on May 15-16, 2008 at the Hasso-Plattner-Institute (HPI) in Potsdam, Germany. It was an exciting opportunity for researchers and prac- tioners interested in self-sustaining systems to meet and share their knowledge, experience, and ideas for future research and development. S3 provided an - portunity for a community to gather and discuss the need for self-sustainability in software systems, and to share and explore thoughts on why such systems are needed and how they can be created and deployed. Analogies were made, for example, with evolutionary cycles, and with urban design and the subsequent inevitable socially-driven change. TheS3participantsleftwithagreatersenseofcommunityandanenthusiasm for probing more deeply into this subject. We see the need for self-sustaining systems becoming critical not only to the developer's community, but to e- users in business, academia, learning and play, and so we hope that this S3 workshop will become the ?rst of many.

The people respond to Men of Cotta... "What the hell is this?" - Dr. Alphonso J. Schlactenhaufen, PhD Chancellor, Castle Cyber University "Dad would be so proud." - Gypsy Rose Rotzinger "Just about the biggest thing that's happened to Burgfort since the College folded " - Christian Schmedeman Owner-operator, KWBG-FM "I got the Cotta manuscript in the mail. I hasten to point out it was unsolicited. I haven't yet had a chance to read it, but the pictures are interesting. Do you pay for reviews?" - Colt Swann Literary Editor, The New York Dispatch
